Thank you all for your response.
Got one more query,
When I'm trying the below command
Select UPPER('Mass')
I'm getting MASS as output .
But when I created the column with generated always constraint
For example
Alter table xyz add column xyz varchar(800) generated always as (UPPER(content)) stored
Here content is original string coming from the table
The output is coming as 'µass" when I am selecting the data from the table
Even When I try to use collat C or ucs_basics I'm getting the same when I select the data from the table
But when I select the data explicitly through UPPER netword like select UPPER('Mass') then I'm getting expected output such as MASS
Would request you to please suggest the ideas to resolve this issue.
Thanks,
Sai Teja

Data seems to be the same, function behaviour is what seems different.

Maybe because unicode has GREEK CAPITAL LETTER MU ( 924, which looks
like capital M ), GREEK SMALL LETTER MU ( 956 ) and MICRO SIGN ( 181,
which looks like small mu ) while windows-1252 only has 0xB6 as micro.
OTOH Windows-1253 ( greek ansi ) has all three.
If your small mu are really micro-sign ( which is suspected if youused
1252 ) maybe changing them to that helps ( but I do not have the
resources to test that on hand ).
